R/W Default Description
Local GPIO Output Value This value is output on the
RW
0
GPIO pin when the GPIO function is enabled, the local
GPIO direction is Output, and remote GPIO control is
disabled.
Remote GPIO Control
1: Enable GPIO control from remote Deserializer. The
RW
1
GPIO pin needs to be an output, and the value is
received from the remote Deserializer.
0: Disable GPIO control from remote Deserializer.
